Seventy percent of moms with kids younger than age 18 work. Despite the huge number of us who both parent and pay bills, it's undeniable that this balancing act does not come without numerous challenges. It's with that in mind, and because Mother's Day is this weekend, that WalletHub has compiled its list of 2017's Best & Worst States for Working Moms.

Researchers looked at 13 key metrics—including child care quality and cost, and the median salary for women—to rank all 50 states and the District of Columbia. Here's what they found.

New York has the highest day-care quality score, while Idaho ranks lowest. Other states with high-quality day care include Washington, North Dakota, Oklahoma, and Texas.

Mississippi boasts the lowest child-care costs as a share of the median women's salary, at just 9.87 percent. The District of Columbia has the highest at a whooping 26.70 percent. New York, Alaska, Nevada, and Rhode Island also come in high on the list.

But it's worth considering that D.C. has the most pediatricians per 100,000 residents. Idaho fares worst here, but then again, it is an area that is far less densely populated.

South Dakota is a star state when it comes to the ratio of female executives to male executives. Utah has the lowest.

Maryland was determined to have the lowest share of single-mom families with children younger than 18 in poverty. Sadly, Mississippi has the highest.

Virginia is the place to live and work for moms who want the highest median women's salary of $42,814. Hawaii registers the lowest at $22,645. (All were adjusted for cost of living.)

The states with the lowest gender pay gap include Hawaii, D.C. Florida, Delaware, and New York. The highest: Wyoming.

North Dakota boasts the lowest female unemployment rate, at just 2.4 percent. D.C.'s rate is the highest at 7.5 percent.

The takeaway: In most cases, you aren't going to move to another state based upon this report. But WalletHub's analysis hopes to spur progress in narrowing the income inequality gap between men and women in the workplace and improve upon the child care crisis in this country.
